Over the decades, Barbie has been outfitted in all manner of costumes, uniforms and professional attire, but the addition of a Girl Scout uniform to the famous doll's wardrobe has been met with outcry by some groups.

In a $2 million deal, the Girl Scouts partnered with Mattel, the toy company that makes Barbie, to create a Girl Scout-inspired Barbie doll, and the Girl Scout's first corporately sponsored participation patch. The partnership began in 2013, and the new Barbie is set to hit store shelves this week, according to Parade.

Girl Scouts can earn a "Be anything, Do everything" patch inspired by Barbie. Scouts must complete a booklet about career choices, according to Parade. They must match character traits with careers, and come up with an idea for their own Girl Scout badge.

They do not need to purchase the new Barbie to get the patch. The booklet can be downloaded online and they can download or send away for the patch once they've completed the booklet.

So why the controversy?

"Barbie is basically a terrible role model for girls, and she's not about what the Girl Scouts' principles are, which have to do with leadership and courage," said Susan Linn, a psychologist and director of the Campaign for a Commercial-Free Childhood. On Monday, Linn told TODAY that Barbie in a Girl Scout uniform sends the wrong message.

In an Associated Press interview in March, Linn expanded on the group's complaint:

"Holding Barbie, the quintessential fashion doll, up as a role model for Girl Scouts simultaneously sexualizes young girls, idealizes an impossible body type, and undermines the Girl Scouts' vital mission to build 'girls of courage, confidence and character."

The Girl Scouts have countered criticisms of the new doll, saying Barbie sends girls positive messages.

"Girls and moms alike associate this doll with the outdoors, camping, giving back in your community, and we think that those are really positive messages to all of our girls," Kelly Parisi, a spokeswoman for Girl Scouts of the USA, told TODAY.

In a 2013 press release about the new doll, the Girl Scouts called Barbie a "trailblazer."

"The participation patch is designed to inspire the next generation of female leaders, encouraging girls to explore endless career possibilities through exciting new program activities," the press release says.

"We are tying the fun girls have playing with Barbie to an opportunity to gain insight into the careers of today and tomorrow, through patches and discovery along the way," Girl Scouts of the USA CEO Anna Maria Chávez said in a statement to Parade.

One Girl Scout mother told TODAY that she didn't think the new doll and the sponsored patch were a big deal.

"I think if the girls didn't identify with Barbie, it might create a problem for us as parents, but the girls love them," she said. "It represents what they love."
